This paper describes that the film formation and shear properties in MAC lubricant were investigated in order to understand the lubrication mechanism under the full-starved conditions. In the tests, a point contacted sliding-rolling tests were conducted, and the film thickness was measured by the optical interferometry method. The results showed that under full-flooded conditions the film thickness decreased with the slide to roll ratio, and that the shear stress increased with the slip ratio. It was also shown that under full-starved conditions the film thickness decreased with time while the wear was not caused in the test duration. In addition, the shear stress from 15 s after the start did not depend on the shear rate and was almost same value corresponded to 18 MPa. These results suggest that the shear properties under full-starved conditions was identical to that in the solidification film.
